the one you can afford don't confuse a power "conditioner' with a transformer or an Uninterupptible Power Supply - think of it as a standard power strip that fits nicely into your rack. I chose a model with pull out lights and a dimmer control - handy when your at a gig, very low lighting, and you need to see something on your FX unit that the LCD doesn't report I have a Furman something-or-other 8 way in one rack and a Chandler something-or-other 12 way in another rack. Both have lights with dimmer control. I have Tripp Lite UPS's to plug those into. The UPS's cannot keep me going during an extended power failure but they do allow me to perform a "gracefu"' shutdown when a failure occurs there's a lot of hype about power conditioners - most of it is BS
they are worth the convenience when you have multiple devices in a rack and you don't want a wad of cables hanging out of the back, and the lights have been useful to me when I had to tend to some recalcitrant hardware on a dimly-lit stage. If these scenarios do not aply to you then buy some new strngs and instrument cables instead
I agree. A $2 power strip with a circuit breaker and a small Maglite (2 AA cells) serve the same purpose for me.
Oh yeah, I forgot to mention my road rig also includes a $4 outlet tester. I bought that right after the first time I experienced the blue spark jumping from the microphone ball to my upper lip!
